WILLIAM W. SEELEY, OF ALBANY, NEV YORK.

BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 374,207, dated December 6, 1887.

Application filed January 3, 1887.

To all whom it may concern.-

Be it known that I, WILLIAM W. SEELEY, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Baling-Presses, of which the following is a specification.

My invention relates to improvementsin that class of baling-presses in which a steam engjne or other motive power is employed forimparting a rotatory motion to the driving-shaft of the press; and it consists of the novel combination of parts herein described.

In the accompanying drawings, which are herein referred to and form part of thisspecification, Figure 1 is a plan view of the power end of my baling-press; Fig. 2, a side elevation of same, with parts of the framing broken away to show underlying parts; Fig. 3, a longitudinal section of Fig. l at the line XX; Fig. 4, an enlarged horizontal section of part of the frame-work of the press, showing a plan view of the plungerclamping device and Fig. 5, an enlarged side elevation of part of the cam-wheel for operating the press-plunger.

As represented in the drawings, A is the framework of the press, of which only the parts affected by my invention are shown B, a driving-shaft fitted to rotate in the boxes b, and provided with a pulley, b, or other appliance through which motion derived from a suitable motive power can be imparted to said shaft. The shaft B is also provided with apair of pinions, b", which engage with the 5 journaled in the brackets c.

gear-wheels O, that are secured to a shaft, 0,

A pinion, e", secured to the shaft 0, engages with a gear-wheel,

' D, that is secured to the shaft d, havingjournals in the brackets d. The shafts c and d are yoked together by the stationary stay-bars E, having eyes at each end, in which said shafts are free to rotate, and by means of said stay-bars the shaft d is supported to withstand the transverse strain to which it is subjected. The wheel D is provided at both sides, at diametricallyopposite points, with sliding arms F, which are fitted. to move in snugs (1 formed on said wheel. Each pair of said sliding arms, on the opposite faces of said wheel, are fastened together by the rivetsf, so as to move as one piece, and the outer ends of the innermost rivets are provided with friction-rollers f, for a purpose hereinafter explained. Springs f Serial No. 2; (No model.)

may be employed for the purpose of forcing the sliding arms F to extend outward beyond the perimeter of the teeth of the gear wheel D,- and when so employed said springs are preferably inserted in recesses d, where one end will rest against an abutment, cl, and the opposite end will exert pressure against one of the rivets f. The sliding arms F derive their required movements from stationary cams e and 6', attached to the stay-bars E. The major part of each cam e is concentric with the center of the shaft (2, and while the friction-rollersf are passing over the said concentric part of the cams e the sliding arms F will remain in their projected positions, as shown in Fig. 2. The opposite side of both cams e is cut away to form, in conjunction with the cams e, curved grooves e", which bend inwardly toward the shaft d, so that when thefriction-rollers f are passing through said grooves the pair of sliding arms F, to which said rollers are attached,will. first be moved inwardly, so that their outer ends will not pro ject beyondthe points of the teeth of the wheel, and then forced outwardly into their projected positions, hereinabove referred to. Near the ends of the shaft cl two cranks, G, are loosely fitted so as to swing freely on said shaft, so that the crank-pin g, which is secured in both of said cranks, will pass through an arc of about one hundred and twenty degrees, the travel of said crank-pin being above the shaft d. The crank-pin g is preferably provided with a friction-sleeve, g, which is fitted to rotate on said pin between the pitmen H, and with which the sliding arms F engage. Two pitmen H are connected at one end to the crank-pin g, and at the opposite end to the reciprocating plunger I. Said pitmen are arranged at opposite sides of the gear-whcelD, and they form one part of a toggle -joint of which the cranks G are the complement. The plunger I is fitted to slide in the pressingchamber a of the press with sufficient freedom to permit the resilient action of the compressed material to cause said plunger to rebound toward the shaft (1; and in order to prevent this rebounding movement of said plunger from being carried too far a movable cross-bar, J, is arranged across the lower part of the pressfrainc, near the point where the rebounding movement of the plunger should terminate,

and where the said plunger will strike it before the termination of said movement. Rodsj are attached'to each end of the cross-bar J and are jointed, as at k, to wipers K, which are pivoted, as at k, to the sill-pieces of the pressframe. Clamps L are hinged at Z to each side of the press-frame, in such position that by a slight movement they can be brought into frictional contact with opposite sides of the plunger I.

The operation of my press is as follows: The plunger I being at the outermost point of its stroke, as shown in Fig. 2, and the drivingshaft B being continuously rotated to impart,

through the train of intermediate gears, the

required motion to the wheel D, which rotates in the direction indicated by the arrow in Fig. 1, as the pair of sliding arms at the part of the wheel D, then at the rearmost end of the press, are carried upward by said wheel, they are brought into engagement with the crank-pin g, and by the continued motion of the wheel D the cranks G and pitmen II are moved to force the plunger I inwardly to compress the material in the pressing-chamber a. The engagement ofthe sliding arms F with the crank-pin g continues until the crank pin has nearly reached the level of the center of the shaft d, or in the position shown in Fig. 3. When this point has been reached, the sliding arms F will have been retracted by the friction-rollers f entering the grooves 6, thereby freeing the crank-pin g from said sliding arms. Thereupon the resilience of the compressed material will cause the plunger I to rebound toward the rearmost end of the press, thereby restoring the cranks G and pitmen H to their normal positions, as shown in Fig. 2, where they will be ready for a re-engagement with the next pair of sliding arms as they are brought around by the rotations of the wheel D. As the plunger I nearly reaches the termination of its rebounding movement, it will encounter the cross-bar J, and will force the cross-bar slightly back, as indicated by dotted lines in Fig. 4, and thereby the wipers K will be swung inwardly to move the clamps L to pinch against opposite sides of the plunger I, and thereby the rebounding of the latter will be effectually stopped.

As shown in the drawings, the wheel D is provided with two pairs of the sliding arms F; but, when preferred, either a greater or lesser number of pairs of said arms may be employed, and thereby a'more or less frequent movement of the plunger I will be produced by a given number of revolutions of the wheel D.

I claim as my invention' 1. In a baling-press, the combination, with a wheel, D, provided with sliding arms F, of the swinging cranks G and their connectingpin 9, and the pitmen H, connected to said cranks by the crank-pin g, the said sliding arms alternately engaging and disengaging with said crank -pin, as and for the purpose herein specified.

2. In a baling-press, the combination, with a wheel, D, provided with sliding arms F, and the stationary cams e and e, the said sliding arms being moved inwardly and outwardly by means of said stationary cams, as herein described, ot' the swinging cranks G, connected together by the crank-pin g, loosely fitted on the shaft (1, and the pitmen H, connected to said cranks by means of the crank-pin g, the said sliding arms alternately engaging and disengaging with said crank-pin, as and for the purpose herein specified.
